IMPROVEMENT IN RAILWAY CAR-COUPLINGS.

Specification forming part of Letters Patent No. 120,746, dated November '7, 1871.

To all whom it may concern:

Be it known that I, LAWRENCE IBECK, of Kickapoo, in the county of Peoria and State of Illinois, have invented a new and valuable Improvement in Car-Couplings; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specifi cation, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a vertical section of my invention. Fig. 2 is a front view.

This invention has relation to car-couplings; and the novelty consists in the construction and arrangement of devices for the purposes of adjusting the coupling-links to suit car-platforms of different heights, as hereinafter described.

Referring to the accompanying drawing illustrating this invention, A represents the body or platform of a car. B shows the bumper-head, constructed with a beveled projection, C, On top to hold the coupling-link of the other car. D designates the coupling-link hinged to the sides of the bumper and projecting beyond its head. Said Vlink is furnished with a transverse bar, d, to

which is hinged a tube or box, d1,inclosing a spiral spring, d2. A piston, E, enters the upper end of said tube and rests on the spring d2. Its rod is pivoted to a lever, F, which is pivoted to the end of the car and is provided with a dog, G, which has a stud, g, adapted to fit holes in a segment-plate, H, so as to hold the lever F in any position, and through it hold the link D. The object of the spring d2 is to render the coupling elastic. The movement of the lever raises or lowers the link to fit different heights of carplatforms. I represents keys pivoted to the side of the car, and designed for use as substitutes for the dog G and perforated plate H. J represents a guard or guide to the lever F. The tube d1 has a cap, d3, screwed on its lower end, which is adapted for the insertion of the spring. When two cars are coupled together one of the links D falls over the projection G on the opposite bumper-head, while the other link rests against the opposite tube, as shown in Fig. 1.

What I claim as my invention, and desire to secure by Letters Patent, is-

In car-couplings, the tube d1, hinged to the link D, spring d?, piston E, and lever F, in combination with the dog G and perforated plate I,

` substantially as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
